SEPARATOR FOR FUEL CELL AND METHOD FOR MANUFACTURING THE SAME

摘要

A separator for a fuel cell and a method for manufacturing the same comprise two sheets of metal plates integrally formed to minimize contact resistance between an upper metal plate and a lower metal plate. The method for manufacturing the separator includes steps of preparing an upper metal plate and a lower metal plate, each plate having opposing main sides, and applying a coating liquid containing a polymer composite material on both sides of the upper and lower metal plates, to form first and second composite material layers on both sides of the upper plates and third and fourth composite material layers on both sides of the lower plates. The method further includes stacking the upper metal plate on the lower metal plate, before drying the respective composite material layers, and integrally bonding the second composite material layer and the third composite material layer to form a single intermediate composite material layer.

1. A separator for a fuel cell, the separator comprising:
an upper metal plate having opposing main sides including a first and a second composite material layers coated on both sides thereof; and a lower metal plate having opposing main sides stacked on a bottom of the upper metal plate and including a third and a fourth composite material layers coated on both sides thereof, wherein the second and third composite material layers between the upper metal plate and the lower metal plate are integrally bonded, before being solidified, to form a single intermediate composite material layer.
